(Pocket-lint) – Huawei’s second generation of its foldable smartphone comes in the form of the Mate X2, while Xiaomi’s foldable phone is called the Mi Mix Fold.
Both follow a similar design to the Samsung Galaxy Z Fold series after Huawei changed the format of the folding device from its predecessor – the Mate X and Xs- moving from a foldable display on the outside, to an inward folding display.
If you’re in the market for a vertically folding smartphone, here is how the Xiaomi Mi Mix Fold, Huawei Mate X2 and the Samsung Galaxy Z Fold 2 compare.
Design
- Mi Mix Fold: 173.3 x 133.4 x 7.6mm unfolded / 173.3 x 69.8mm x 17.2mm folded / 317g (Black) 332g (ceramic)
- Mate X2: 161.8 x 145.8 x 4.4-8.2mm unfolded / 161.8 x 74.6 x 13.6-14.7mm folded / 295g
- Z Fold 2: 159.2 x 128.2 x 6.9mm unfolded / 159.2 x 68 x 16.8mm folded / 282g
The Xiaomi Mi Mix Fold has a vertical folding display in a book-style design, like the Huawei Mate X2 and Galaxy Z Fold 2. It comes with a glass or special edition ceramic back and there is a prominent camera housing in the top left corner. There’s a metal frame, large display and a single punch hole camera in the top right corner when folded.

Conclusion
The Xiaomi Mi Mix Fold and Huawei Mate X2 is only available in the Chinese market at the moment but while the Mate X2 is a little more expensive than the Samsung Galaxy Z Fold 2, the M Mix Fold is cheaper.
On a spec-by-spec comparison, these three devices are similar and while the Xiaomi Mi Mix Fold tips the scales in several areas, the other two devices have their fair share of wins too.
The Xiaomi Mi Mix Fold has larger displays both interior and exterior than both the Huawei and Samsung. It also offers the most advanced Qualcomm chipset, the largest battery of the three devices, the fastest wired charging capabilities and it has an interesting camera setup with its liquid lens.
The Mate X2 arguably has a more streamlined design, an extra camera on the rear and a wide-angle front camera. It also has only fractionally smaller displays than the Mi Mix Fold.
The Galaxy Z Fold 2 has more RAM than the Mate X2 but the same as the Mi Mix Fold. It also has a higher refresh rate on the internal display though and it offers a more user-friendly software experience, as well as supporting Google services – the latter of which the Mate X2 does not offer. The Z Fold 2 has less cameras than Huawei but the triple rear camera does offer great results.
The Samsung is more widely available than both the Mate X2 and the Mi Mix Fold so while the Mi Mix 2 and Mate X2 might win on some specification areas, you’ll need to live in China to get your hands on them for now. It’s also worth remembering the Galaxy Z Fold 3 is tipped for a July 2021 launch.
